Phylogenetic Investigator Phylogenetic Investigator (PI) is a software package designed to facilitate creative problem-solving in phylogenetic analysis for the purpose of teaching and learning phylogenetic inference. Users can identify characters and states, polarize characters, and engage in directed-search phylogenetic tree construction.
PI also allows the user to
* make inferences and represent them one step at a time
* vary representational features of their trees (such as angle of divergence and time betweeAuthor(s): No creator set

Slope (m) of a line (Coordinate Geometry) An interactive applet and associated web page that demonstrate the slope (m) of a line. The applet has two points that define a line. As the user drags either point it continuously recalculates the slope. The rise and run are drawn to show the two elements used in the calculation. The grid, axis pointers and coordinates can be turned on and off. The slope calculation can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed as it appearAuthor(s): John Page

Distance from a point to a vertical or horizontal line An interactive applet and associated web page that demonstrate how to find the perpendicular distance between a point and a line that is either vertical or horizontal, given the coordinates of the point and the equation of the line. The user can set the orientation of the line and position, along with the location of the point. As the line is altered or the point dragged, the distance is recalculated. The grid and coordinates can be turned on and off. The distance calculation can be turned off tAuthor(s): John Page

Koch's Crickets: A Study in Etiology Students apply Koch's Postulates in an attempt to discover the causative agent of "Pink Plague" a disease that has struck a group of commercially raised crickets. During the course of this exercise the students will isolate the suspected pathogen from one of a group of infected crickets. They will then characterize the isolated organism and use it to infect a new group of crickets to see if they can reproduce the same symptoms in the newly infected group. Reisolation of the suspected pathogen frAuthor(s): No creator set
